Arnold Arboretum of Harvard University
Date Idea, Kid Friendly
Late April through May
Enjoy the lilacs over four weeks of bloom (typically late April through mid-to-late May). We invite you to visit during these weeks of peak lilac bloom, but request that you practice social distancing from one another and respect our plants. If the landscape appears to be too crowded for safe visitation, please return another time.
In keeping with CDC and Harvard COVID-19 guidelines for large gatherings, the Arnold Arboretum of Harvard University will not hold Lilac Sunday 2021. Formal events and public programming related to the Arboretum’s celebration of lilacs have been postponed until spring 2022, when the Arnold Arboretum will celebrate its sesquicentennial and 112th observance of Lilac Sunday. Picnics will not be permitted on this or any day.
Attend a virtual tour on Tuesday, May 11 at 1pm with longtime Arboretum docent and lilac expert Chris McArdle! Learn more here.
